Hello everyone, surfing the net I came across the idea to write a kindle book and sell it on amazon. Due to the fact that you do not have to spend any money I gave it a try. I wrote a little poker guide talking about pot odds calculation because I love to play poker. I published it at the end of january and it did not take a long time until I made my first sale :-). I was very happy because it was the first time that I earned money online - amazing feeling!! :-). All in all I sold 25 books and
